Pinned topicWorkflow assignment based on owner group field

In TSRM 7.2, I'm trying to make a workflow assignment (based on the owner group field ) to all people in that person group. In order to do it, I create a function this way:

Type: A data set related to the record

Object: SR

Value: :OWNERGROUP.ALLPEOPLEINPERSONGROUP

Broadcast: Yes

I did it this way, because I saw an off-the-shelf function that did this but sending an e-mail to all person group members (not a broadcast function). However, it does not work, I receive the following error:

BMXAA440 a nested exception the process failed

BMXAA4176E - Attribute ALLPEOPLEINPERSONGROUP does not exist

Alternatively, I tried :OWNERGROUP value but the assignment is not being made and the workflow cannot be reassigned, so it is necessary to stop it.

What is the actual variable that should be in the value field, so that the workflow gets assigned to every person in the owner group field?

PD: I attached an image that shows the function app while creating one.
